Presumably born in Poland, Nadzia later moved to the UK and settled in the unnamed city where the show takes place. At some point prior to the first series, she was employed by the Sunflower Cafe as a waitress.
A Disastrous Affair
Nadzia is one of the waitresses on shift when DCI Anthony Gates and Jackie Laverty are having breakfast. When Gates intervenes to stop a mugging from taking place outside the cafe, Nadzia calls the police and then gives him his food on the house.
Chief Superintendent Ted Hastings later interviews Gates in connection with the minor charge of failing to declare a gratuity from Wojcik in the form a free breakfast, and issues him a yellow notice.
She is later interviewed at work by DS Steve Arnott regarding the incident with Gates. Throughout their conversation there are flirtatious undertones.
